The treatment of wool-scouring effluent by polysulfone hollow fiber ultrafil- tration was studied with regard to the influence of temperature,pressure,concen- tration and flow rate of the effluents.By means of ultrafiltration treatment,the grease、total solid and COD containts of the effluents can be reduced by more than 90%,80% and 85% respectively.The treated effluents can be reused by adding small amount of detergent(about 30% of the amount originally added). The construction of the ultrafiltration appara...
